Hello everyone, I just bought the unlocked/Jail broken 16G (1st generation) and firmware 1.1.4. Right now, I can call, go to internet, play summerboard, customize, installer and so on. EXCEPT,when I plug in my iphone to computer, both pc computer and Itune are not dectecting my iphone. I know that my usb cable work well because at that time I plug in my friend's unlocked iphone 8G in to my computer, and it detected my friend's iphone. I don't know why. I just do everything to try itunes and my computer dectect it. There are all of ways that I have researched from all resources from all of website: 1) I installed the newest itunes 8, but it would not work for me 2) I tried to restore by holding Home button and power for 10 seconds, and released power but still held home buttton, but this way didn't help me out even I tried on either itunes 7.7 or itunes 7.6 and itunes 7.5. 3) I went to Computer Management=> service=> stop "Apple Mobile Device" then start it again. After that, I opened itunes and plug in my iphone but this way still didn't help me out. 4) I also tried to use Ziphone and hopefully Ziphone software could dectect my iphone, but it didn't dectect my iphone because I think Ziphone can dectects it when Itunes recognizes first. 5) One more thing, I should mention when I held a home button while the logo apple were appearing. Then I looked at in my screen iphone, i saw the picture of the USB cable and the arrow pointing to itunes appeared, but my pc computer didn't pop up anything.
